TO ALL WHOM IT MAY CONCERN. I

Be it known that I, LoUIs FITZMAIER, of the city, county, and State of New York, have invented a new and improved Method of Ornamenting Tin or other Metal Plates and Articles made therefrom; and I do hereby declare the following to be a full and exact description thereof.

The nature of my invention consists in transferring any desired drawing from a lithographic stone on paper, and from thence on the tin or'other metal plates or articles, by using a certain process hereinafter described.

To enable others skilled in the art to make and use my invention, Iwill proceed to describe its construction and operation. l

The drawing which I wish to transfer is first made on a lithographic stone, by means of lithographic ink or chalk. It is blackened and etched in the usual manner. I then take paper and prepare the same like the usual lithographic transformingpaper, by taking three parts of flour, one part of starch, and some water. I then boil this mixture, and pour more water into it,- until a fiuid is obtained which when cooled may be trans ferred by a brush. I then transfer this mixture evenly by a brush on one side of the paper, and leave it there until it dry, when I plaitit on the other side by a hot plaiting-iron, in the same manner in which starched linen is plaited. I then take a composition, consisting of about two parts No. 3 lithographic varnish, one part No. 1 lithographic varnish. one-half part calcined magnesia, one half-part chrome-yellow, well mixed and rubbed together. The black color from the stone is then removed by turpentine, and this yellowish mixture is then uniformly rubbed over the drawing on the lithographic stone by means of a hand-roller, whereby the stronglymarked parts of the drawing receive no more of the said mixture than the finer parts of the same. I then obtain a yellow impression frorn the stone on prepared paper. After obtaining an impression from the drawing of the lithographic stone, I put gold foil or silver foil over the impression after having removed the paper from the stone. I then again rub' the stone uniformly with thesaid yellowish mixture, and again place a second sheet of prepared paper on the same, on the top of which I place the said first impression prepared with gold foil or silver foil, and draw both the first impression and the prepared paper through a usual lithographic press. When I desire a. shaded design the second impression must be on transparent paper. I now mik Demar varnish, boiled linseed oil, and turpentine, and wet the tin or other metal plate or article to be ornamented with this mixture uniformly over, the whole surface. Ithen put on the said tin, &c., that side of the first impression on which the gold foil or silver foil is. The other side of said impression I moisten with water; I then roll overthe moist side of the paper by a wooden flannel-covered hand-roller, and then withdraw the paper fromthe metal, when the gilded or silvercd impression will have remained clearly and distinctly on the surface of the tin or other plate or article.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-e 1. Ironing prepared paper on its back side by means of a hot planing-iron, for the purpose of obtaining a straight and glossy appearance of the same, substantially in the manner and for the purpose described.

2. The use of a composition consisting of lithographic varnish and chromeyellow, substantially in the manner and for the purpose described.

8. Rolling over the moist side of the paper by a wooden flannel-covered handroller, whereby a uniform impression of the drawing is produced on the tin, &c., substantially as described,

LOUIS FITZMAIER.
